THE DEVELOPMENT OF THE THEORY OF SOIL CONSOLIDATION IN THE U.S.S.R., 1917-1967

THE DEVELOPMENT OF SOIL CONSOLIDATION THEORY HAS RECEIVED MUCH ATTENTION IN THE U.S.S.R., BEGINNING WITH THE BASIC WORKS OF GERSEVANOV (1931). THE LATEST WORKS IN THIS FIELD ARE DEVOTED TO THE CONSOLIDATION OF MULTIPLE-PHASE SOIL SYSTEMS, TAKING INTO ACCOUNT THE DEFORMABILITY OF ALL PHASES OF THE SOIL (INCLUDING THE CREEP OF THE SOIL SKELETON), THE DEGREE OF SATURATION, THE NATURAL COMPACTION AND THE STRUCTURAL NATURE OF THE SOILS (TSYTOVICH AND ZARETSKY, 1967). THE PAPER TREATS IN DETAIL THE MAIN STAGES OF DEVELOPMENT OF THE FILTRATION CONSOLIDATION THEORY AS FORMULATED BY TERZAGHI, GERSEVANOV AND FLORIN, AND IN THE MORE GENERAL FORMULATION THE FLORIN-BIOT THEORY OF VOLUMETRIC FORCES AND THE GENERALIZED THEORY OF VOLUMETRIC FORCES. THE LAST OF THESE TAKES INTO CONSIDERATION THE RHEOLOGICAL PROPERTIES OF SOILS AND IS BASED ON THE HYPOTHESIS OF THE PROPORTIONALITY AND COAXIALITY OF THE DEFORMATION TENSOR TO THE TENSORS OF THE TOTAL STRESSES AND THE PORE PRESSURE. THE RESULTS OF THE THEORETICAL SOLUTIONS ARE ANALYSED AND A NUMBER ARE COMPARED WITH EXPERIMENTAL DATA. /AUTHOR/
